Mark Levinson No.390S CD Processor

It was 20 years ago that I appeared on one of the UK's equivalents of NBC's Today show to comment on the launch of CD. I wanted to talk about digital technology, but my host was more interested in the medium's lack of surface noise, which he demonstrated by showing that a disc smeared with butter and marmalade—this was breakfast television, remember—would play without skipping. (Actually, it wouldn't play; after the jammy CD was loaded, the program cut to a pretaped segment in which the player had a pristine disc inside it.)

Meitner IDAT D/A processor

There are as many ways of designing a digital-to-analog converter as there are engineers. One approach is to select parts from manufacturers' data books and build the product according to the "application notes" provided by the parts manufacturers. This is the electronic equivalent of a paint-by-numbers kit.

A more creative engineer may add a few tricks of his own to the standard brew. Bigger and better regulated power supplies, careful circuit-board layout, tweaky passive components, and attention to detail will likely make this designer's product sound better than the same basic building blocks implemented without this care. Indeed, the vast range of sonic flavors from digital processors containing very nearly the same parts attests to the designer's influence over a digital processor's sound.

Meitner MA3 Integrated D/A processor

Music lovers (and reviewers) long for those listening moments when their entire being lights up with joy. For me, that divine spark surfaced unexpectedly one February afternoon when, late for an appointment, I dashed into the music room, searching for my keys. That's when I heard a bit of the 24/96 WAV files of this issue's Recording of the Month, conductor Andris Nelsons's mammoth survey of the complete orchestral works of Richard Strauss, which I'd cued up on repeat to help Meitner's MA3 integrated D/A converter ($10,500) settle in.

Merging Hapi MkII multichannel digital processor

I've been running a 5.1 system for years. Recently, I expanded it to 5.3 with the addition of two more subwoofers. This system is manageable with one of my eight-channel DACs.

Even more recently, I dipped my toe into Dolby Atmos, which made it necessary to lash up at least four more channels. That was a big problem, since neither JRiver nor Roon can support and sync more than one output device at a time, and the multichannel DACs I already owned tap out at eight channels.

I turned to the Arvus H2-4D Renderer, which offers 16 channels of digital output over AES3 and 16 channels of balanced-analog output. This worked, but piping everything through the Arvus meant forswearing DSP, including DiracLive. I really needed a DAC with at least 12 channels.

The Merging+Hapi has been around for years...
